Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
15 Mar - 05 Oct 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
GLP compliance:
yes (incl. certificate)
Key result
Test procedure:
burning rate test: preliminary screening test
Moisture (wt %):
0.013
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Test item did not self-ignite, a small endothermic event was observed between 70 and 80 °C, which equated to its melting point. No trace of test item remained in the sample basket and charred black solid was found on the base of the sample holder.

Description of key information

non flammable

no pyrophoricity

not flammablility on contact with water

not self-heating

Key value for chemical safety assessment

Flammability:
not classified

Additional information

No ignition in the preliminary burning rate test (EU Method A.10).

Based on experience in handling and use pyrophoricity and flammability on contact with water are not to be expected.

The substance has a melting point of 77.5 °C; self-heating behaviour is not relevant for substances that are completely molten at 160 °C.

Justification for classification or non-classification

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification:

No ignition in the preliminary burning rate test (EU Method A.10).

Based on experience in handling and use pyrophoricity and flammability on contact with water are not to be expected.

The substance has a melting point of 77.5 °C; self-heating behaviour is not relevant for substances that are completely molten at 160 °C.
